Engine
Check section 8 of the Kawasaki Service Manual.
The above section contains a troubleshooting guide for engine and auxiliary systems. It also has a special
section on troubleshooting the starter motor.
Wiring Harness
•
Symptom: The starter motor works but the engine does not turn over.
Suggested procedure:
1.
Check the fuel level and the position of the fuel valve lever.
2.
If OK, disconnect the hose, hold the end in a container and crank the engine. If no fuel comes out,
the fuel pump is faulty or the line is blocked. If fuel does come out;
3.
Remove the air filter cover and air filter. The fuel valve can be seen in front of the carburetor. With
the seat switch depressed, hold a finger against the valve and turn the ignition switch to RUN. A
sharp click will be felt if the valve opens (the carburetor will then be getting fuel). If not;
4.
Disconnect the main harness from the engine. Locate the red and violet wires in the main harness
connector. Attach the red (+) lead from a voltmeter to this connector, and ground the black (-) lead
to the mower chassis. With an operator in the seat and the ignition turned to RUN, the voltmeter
should register 12 volts. If it does, the fuel valve is faulty. If there is no voltage, the problem may be
in the harness wires, the connectors or the ignition switch.
•
Symptom: The starter motor does not work.
Suggested procedure:
1.
Check that the brake lever is in the on position, that the blade engagement switch is pushed in,
that the motion control levers are in the neutral slots and that there is someone on the driver's
seat. If all correct;
2.
Check the 20-amp fuse. If OK;
3.
Check the battery for charge (should be 12 to 13 volts) and that the battery cables are making
good contact at both ends. If OK;
4.
With all levers and switches properly positioned for start and an operator on the seat, hold index
finger and thumb against the start relay, and turn the ignition switch to RUN. A sharp click should
be felt in the relay. If not, change the relay and try again. If a click is felt;
5.
Check that all harness connections to the various switches and the engine are properly
connected. If all OK;
6.
Disconnect the yellow lead from the starter's contactor; attach the red (+) lead of a voltmeter to
this wire, and ground the black (-) lead to the mower chassis. With all levers and switches properly
positioned for start and an operator on the seat, turn the ignition to RUN. The voltmeter should
read 12 to 13.5 volts. If there is no voltage, the harness may have a broken wire, a connection in a
cable connector may be damaged or a switch broken/incorrectly set.
•
Symptom: The ignition fuse blows with the ignition switch at RUN, but does not blow if the engine
connector is disconnected.
Suggested procedure:
1.
With engine connector connected, disconnect the seat and brake switches and the blue and violet
lead from the hour meter. Does the 20-amp ignition fuse still blow when the ignition is now turned
